There is an infrequent problem with the XO-1.5 B2
prototypes where they may not power-up properly.
This would be indicated by the EC rapidly flashing
the battery LED red. It then tries to power up the
laptop again, frequenly succeeding. This will
appear as a flash or two of the red battery LED,
followed by a normal boot.
In an extreme case, it might stay that way for a while.
This is being tracked as #9761 --- please add your
reports to that ticket.
This is likely due to a couple of leakage problems
that we are finishing up. We hunt them down on
each build, but other ECOs have a way of creating
new ones.
